Agenda • Overview of SciFinder Content • Databases • Currency • Search Examples • Topic • Author • Structure • Additional topics and Hands on practice
Databases of SciFinder • CAplus • CASREACT • CHEMCATS • CHEMLIST • MEDLINE/OLD MEDLINE • REGISTRY
CAplus • A CAS literature database containing references to research published in journals, patents, and other sources • Contains Bibliographic, Abstract and Indexing Information – all searchable • 1907 to present (some 1800’s) • Over 23,650,000 records • Updated daily
Medline/Old Medline • A literature database containing references to Medical research published in journals • Contains Bibliographic, Abstract and Indexing Information – all searchable • 1953 to present • About 14,500,00 references • Updated 4 times per week
Registry • Substance Database containing CAS RN, Structures, Chemical Names, Properties, Sequences • 1957 to present • Over 73 Million substances
CASREACT • Database of Reactions • 1840 to present • 8,517,229 Single- and multi-step reactions • Search full or half reactions • Search Reactants, Reagents, Products, catalysts, any Role
CHEMCATS • Quickly and easily obtain current information on commercially available chemicals and their worldwide suppliers • More than 8.1 million products • 734 suppliers • 834 catalogs • Updated upon receipt of new catalog
CHEMLIST • Regulatory information from 19 Government Regulatory lists around the world • 235,034 Inventoried/regulated substances • Updated Weekly
Sources of SciFinder • Over 9,000 journals monitored • Patents (50 patent organizations) • Technical disclosures • Conference proceedings • Technical reports • Books • Dissertations • Reviews • Meeting abstracts • Web preprints • IP.com Journal • Electronic-only journals • etc
Currency of SciFinder • Updated Daily • 1829 Core Journals (over 9000 total) • Bib and abs data within 5 days of receipt • Fully indexed within 21-28 days • 7 core patent organizations (50 total) • Bib and abs data within 2 days of publication • Fully indexed within 27 days
Get Related feature • Starting your search from a text explore • Obtain all the substances indexed in the reference list • Answer set must be <1000 references • Refine with structure fragments or calculated properties • Obtain the older cited references or forward citing references • Answer set must be <500 references
Citation searching • The CAplus database includes citations from journal and patent references • Only from 1998-present • 1997 is in progress • From roman script sources • Over 100 million citations • Older references can be searched as citing references • Results limited to 1998-present
Better substance searching • Pharmaceutical compounds are seldom simple neutral compounds • Beware that salts and mixtures may have their own CAS Registry number • Better to search known compound as an exact structure that as a name • Includes different stereoisomers, salts and mixtures • Can copy/paste a CAS Registry to import the structure
Explore by Structure Search Additional options allow for The inclusion or exclusion of Certain substance classes.
With additional components: 573 Not possible to limit the maximum number of components
Without addl. components: 22 May include some oligomers and radio-labeled compounds
Searching by MF • For addition polymers and most condensation polymers put the molecular formula of the monomers, separated by dots, within brackets and close with an “X” • (C8H8)x for styrene homopolymer • (C8H8 . C5H8)x for styrene-isoprene polymers • For structural repeating units of symmetric condensation polymers put the formula of the repeating unit within brackets and close with an “N” • (C14H12O4)n for polybutylene terephthalate • (C2H4O)nCH4O for -methyl--hydroxy PE
Coordination CompoundsMolecular Weight Easily search coordination compounds with either a molecular weight or a structure.
Coordination Compounds Structure and Refinement The additional options button allows for refinement of answers prior to the search.
